Edit  etc sudoers file either manually or using the visudo application  Remember  System reads  etc sudoers file from top to the bottom  so you could overwrite a particular setting by putting the next one below  So to be on the safe side - define your access setting at the bottom

You need run visudo and in the editor that it opens write   igor    ALL  ALL  ALL   That line grants all permissions to user igor   If you want permit to run only some commands  you need to list them in the line   igor    ALL  ALL   bin kill   bin ps

This answer will do what you need  although usually you don t add specific usernames to sudoers  Instead  you have a group of sudoers and just add your user to that group when needed  This way you don t need to use visudo more than once when giving sudo permission to users   If you re on Ubuntu  the group is most probably already set up and called admin     sudo cat  etc sudoers     This file MUST be edited with the  visudo  command as root             Members of the admin group may gain root privileges  admin ALL  ALL  ALL    Allow members of group sudo to execute any command  sudo   ALL  ALL ALL  ALL    See sudoers 5  for more information on   include  directives    includedir  etc sudoers d   On other distributions  like Arch and some others  it s usually called wheel and you may need to set it up  Arch Wiki     To give users in the wheel group full root privileges when they precede a command with  sudo   uncomment the following line     wheel  ALL  ALL  ALL   Also note that on most systems visudo will read the EDITOR environment variable or default to using vi  So you can try to do EDITOR vim visudo to use vim as the editor   To add a user to the group you should run  as root      usermod -a -G groupname username   where groupname is your group  say  admin or wheel  and username is the username  say  john
